Abstract: 1,008,295. Clearer for drafting-rollers. LUWA S.A. Nov. 6, 1963 [Nov. 6, 1962], No. 43874/63. Heading D1D. Apparatus for cleaning a thread-forwarding roller in a drafting system comprises a stripper lying parallel to the roller and which is caused by frictional contact as the roller rotates both to oscillate and to rise off the roller for a short time, after which it is allowed to fall. The stripper comprises a resilient tube-like sleeve 12 secured by a channel-member 13 to a member 11. This is of trapezoidal suction, Fig. 5 and is connected at each end by a torsional sleeve or spring 29 to a sleeve 27 around the member. This has a bearing- block 28 of nylon &c. and can slide in a slot in a bracket 30. Normally, the stripper contacts the roller along a line L Fig. 5 lying in front of the plane containing the axis of oscillation y and the axis of the roller, the angle d being preferably between 10 degrees and 30 degrees. As the roller rotates in the direction of the arrow, the sleeve 12 is deformed and the member 11 turns in its bearings tightening the torsion sleeve 29, the force set up between the roller and stripper having a component which causes the latter to rise. The torsion sleeve now and sleeve 12 relax and the stripper is freed to fall under gravity into contact with the roller. The stripper is raised more than once during each rotation of the roller, the number of times preferably not being an integer, so that the stripper does not always impinge at the same point. The stripper may be carried by pivotable arms.

IPC: H03F1/34
Filed: 1971-09-21
Abstract: 1369603 Amplifying circuits COMMUNICATIONS SATELLITE CORP 21 Sept 1971 [23 Sept 1970] 43877/71 Heading H3W A predistorting apparatus adapted to precede and compensate a non-linear amplifier, more particularly a klystron, travelling-wave tube or limiter, comprises a feed-forward control means developing a control signal representing the input to the predistorting apparatus, and an attenuation means in which the attenuation is exponentially proportional to the control signal. An input signal Pin, Fig. 1, is split into two equal parts by hybrid circuit 1, the one output 2 of which is again divided into two equal parts by hybrid circuit 4. The outputs 5, 6 are passed to diode attenuators 7, 8 respectively and recombined by hybrid circuit 15 to give an output 16. The attenuation produced by diode attenuator 7 is predetermined by a bias current I 7 . The second output 3 from hybrid 1 is passed via a pre-adjustable attenuator 11 to a crystal detector 12, the output from which is amplified by amplifier 13 and passed to a clamp circuit 14 which limits its maximum value. The output from clamp circuit 14 constitutes the attenuation-controlling input I 8  to diode attenuator 8. Phase compensation.-In addition to compensation for non-linear amplitude characteristics, means are provided for compensating shift of output phase with amplitude in the amplifier to be compensated. A circuit connected in series with the amplitude-compensation circuit (Fig. 1) comprises a hybrid circuit 17, Fig. 2, giving equal outputs 18, having phase-shift- 90 degrees and 19, without phase-shift. Output 18 forms the input to hybrid circuit 20, the first output of which is applied to diode attenuator 22, the attenuation of which is set by means of a predetermined bias current I 22 : the attenuator output forms the input to hybrid circuit 24. The output 19 from hybrid circuit 17 forms the input to hybrid circuit 21, the two outputs 26, 27 of which are applied to diode attenuators 31, 28 respectively. The attenuation of diode attenuator 28 is predetermined by a bias current I 28 , while that of attenuator 31 depends upon a preset bias ZI 31 <SP>1</SP> and also on a bias current I 31  which is developed from the second output of hybrid circuit 20 by means of crystal detector 32 which is followed by amplifier 33. The outputs from diode attenuators 28, 31 are combined in hybrid circuit 30, the output of which forms one input to hybrid circuit 38, which derives a second input from hybrid circuit 24, and provides two outputs in which the phase depends on the amplitude of the input signal to the arrangement.

Abstract: 1,242,482. Gas analysis. BECKMAN INSTRUMENTS Inc. Sept.8, 1969 [Sept.18, 1968; March 27, 1969], No.44321/69. Heading G1B. Apparatus for the analysis of the exhaust gas of internal combustion engines comprises a sampling probe 12 for insertion into a vehicle exhaust pipe 14, the probe leading to a condenser and filter assembly 15 with an inlet 40 passing into an inner chamber 32, the gases being cooled therein by circulation of air from a hose 80 in a surrounding outer chamber 36 so as to condense water vapour in the exhaust gas, which leaves by passage through a filter 44 leading to an outlet 42, the temperature of the gas at this stage being substantially that of the ambient atmosphere, and a conduit 18 leading to an analyzer 16 with a heater 54 located in the conduit 18 to raise the gas temperature above that of the ambient atmosphere whereby condensation of water vapour remaining in the exhaust gas in the analyser is obviated. Gases are drawn through the apparatus by means of a jet pump 20 comprising two concentric tubes 60, 64, the outer of which is connected to the outlet 62 of the analyzer and the inner of which is fed with air from a source of compressed air 90. The source 90 also supplies the cooling air for the chamber 36 of the assembly 15 by way of the hose 80. The probe 12 is preferably a corrugated tube of a length sufficient to cool the exhaust gases to near ambient temperature. It is preferably disposed in a loop from the exhaust pipe 14 to the assembly 15 so as to form an initial water trap for condensed water vapour. Water condensed on the walls of the chamber 32 in the device 15 may be run out through a valve 50 when desired. The analyzer 16 is described as an infrared analyzer with a test cell 26 an infrared source 22 and a thermistor bolometer detector 24. In some cases the heater 54 may be dispensed with if the conduit 18 is disposed in a housing together with the infrared source 22 so that the gases will be heated by this source. A valve 56 is also included in the conduit 18 whereby a calibration gas may be fed to the analyzer 16 from a source 58.

Abstract: 985,826. Projectile fuzes. HOTCHKISSBRANDT. Dec. 12, 1961 [Dec. 19, 1960], No. 44381/61. Heading F3A. In a direct-action projectile fuze a piston 21 is slidable between the inner surface 6 of the fuze body 1 and a carrier 15 and sets back, on firing, against the action of a spring 24a to release locking balls 17, its motion being further damped by the oscillatory passage of a pin 25 in a groove 19 formed in the wall of the carrier 15, Fig. 3. The piston is subsequently driven forwardly to the armed position by spring ;24a and takes with it the carrier 15 and a percussion pin 12 fixed thereto, the pin 25 having engaged a slot 20 at the rear of groove 19. Axial play provided between piston 21 and carrier 15 by movement of pin 25 in slot 20 is such that, on impact, portion 23 of the piston acts as a percussion mass on the carrier 15 and percussion pin 12. With forward movement of the percussion pin 12 a primer support 28 is unlocked and rotates about a pivot 29 (not shown) under the action of a spring 31 to bring a primer 30 on to the line of action of pin 12. Movement of piston 21 is also damped by the creation of a partial vacuum in chamber A during rearward movement and increase of air pressure therein during forward movement.

Title: Improvements in and relating to a method and apparatus for making reinforced plates of synthetic resin
IPC: C10N30/06
Filed: 1966-10-05
Abstract: 1,161,740. Reinforced synthetic resin laminate. LANDBOUWWERKTUIGEN-EN MACHINEFABRIEK H. VISSERS N.V. 5 Oct., 1966 [19 Oct., 1965; 4 Feb., 1966; 13 May, 1966], No. 44501/66. Heading B5N. A method of making a reinforced plate 15 of synthetic resin comprises depositing a layer 13 of liquid resin on one face of each of two strips of foil 3, depositing reinforcing material in the form of pieces of glass fibre on each of the layers 13 of resin, bringing the two strips of foil into confronting relationship with each other with the layers of liquid resin and reinforcing material therebetween, and subjecting the composite strip thus formed to compression to complete the reinforced plate of synthetic resin. In the apparatus shown for performing the method foils 3 from rolls 4 are fed via rolls 7 on to conveyer belts 1, 1a which feed the foils towards the nip of a pair of compression rolls 14. Liquid resin is applied to each foil 3 at the roll 7 by a roller 5 and adjustable scraper 8. Glass threads 11 are cut into pieces by a cutting roll 9 and counter-roll 10 and the pieces fall on to the resin layer 13 to form a fibre layer 12. The foils 3 with the layers 12, 13 thereon are then compressed by rolls 14 to form plate 15. A further quantity of resin may be deposited on the layers 12 before they enter the pressure nip. In a further apparatus the layers 12, 13 are compressed before the pressure nip by an adjustable roll situated above each conveyer belt. The rolls 14 may have at least an outer layer of compressible material or each conveyer may be of compressible material and travel over the associated pressure roll 14. In another apparatus the conveyer belts pass over rolls 14 and also over guide rolls located below these rolls so as to provide an extended nip. In another embodiment a further foil is fed into the nip of the pressure rolls between the layers 12. In this case the finished plate may be separated into two plates.

[Classes 44 and 65 (ii)] [See also Group XVII] A vanity case comprises a shell 10 open at both ends, a hinged lid 16, and plungers 42, 43 slidable into the ends of the shell, and actuation of the plunger 42 releases the lid so that it can be lifted by the other plunger to which it is connected. The plungers slide in shoes projecting inwardly from the side edges of the shell. The lid is flanged and it closes a flanged opening in the shell, and the connection between the lid and the plunger 43 comprises extensions 25 of the side flanges of the lid and a U-shaped rod 61 whose ends pass through a plate closing the open end of the plunger and through apertures in the extensions 25. The barrels of the lid hinge 14 are formed from the lid flange and the flange 12 to the opening in the shell, and these barrels are out of alignment so that when the lid is released, it springs open slightly. The open end of plunger 42 is closed by a plate 48, Fig. 5, out of which are bent spring tongues 49, 50, the tongue 49 pressing on the flange 12 and thus tending to force the plunger outwards and the tip 53 of the other tongue being bent to constitute a latch to engage a corresponding aperture in the lid flange. When the plunger is pressed inwards, lever 50 fulcrums about a projection 52 thereon and disengages projection 53 from a slot in the lid flange. A powder tray 29 in the shell has its side walls flanged outwardly to engage under the flange 12, and a hinged lid 30 to carry a puff forms a tight joint with the tray by means of a gasket 38 held between an outward flange on the lid and a bead 31 on the tray. The lid 30 is held closed by a depending lug on the free edge of the lid which passes through a gap in the opposed flange on the tray and has an offset to engage under the flange. Continued inward movement of plunger 42 after it has released lid 16 causes a kink 56 in a further lever 55 carried on plate 48 to engage under the lug on lid 30 and to force the lug outwards and free the lid which thon springs open slightly. A lip 41 enables this lid to be lifted after it has been released.
